When to water for Renewal Spurs



In the last post I gave you an update about the drought here in California.  The net is we still need a lot of rain in the next 2 months.

2013 our vines were in their 4th leaf (still young and the roots not fully developed) so I was trying to wean them from water to develop the roots better and help the pH of the grapes.  Unfortunately, I went a little to far and the renewal spurs for cane pruning did not fully develop. So, this years crop will be a little smaller than expected…which is OK since we are short of water again and I don’t want to stress the vines so early in their life.  What does that mean for those who don’t know the lingo…in the picture above, the “arms” for his year did not grow enough on some of the vines.  What will I do in 2014?  I’m going to make sure we get enough water until the fruit is “set” which should be enough for 2015.  So much to learn…and I guess you don’t learn unless something happens to you.

Drought Update and our Well Status

drought update


If you have been watching the news you should have heard that California is in a severe drought.  We had about 20% of our normal rainfall last year and the previous years were OK, but not to normal.

Last week (2/6/14-2/9/14) we had our first real winter rain storm of the season and we got 10.7″ of rain.  Unlike where I grew up in Olympia, WA where it rains 1/4″ a day all winter, we get our rain in downpours and then it clears up.  So this was bigger than a normal storm but not unwelcome.  Since we normally get 40″ a year, and this storm put us to 15″, we still have a ways to go to refill our aquifers and get the ground fully saturated.

The other thing you may have heard is that some towns in California will run out of water.  True…depending on where they get their water.  Here in Sebastopol we have a good aquifer that so far has not been affected by the drought.  We use this aquifer for Turtle Vines.  Even though we are a new vineyard we are striving to use as little water as possible.  I probably went to far last year as we did not get enough renewal spurs, but that is for the next post.

We tested our well last week.  It is drilled to 170′ and right now we are at 61′ to the water table.  Later in the year when we begin watering, we will test it again and also find out how fast it recharges after use.  Just FYI…When we purchased our home 6 years ago they said the well was good for 20 gallons/min.  We set up 4 sections in the vineyard and they only draw around 7 gal/min.
